Abstract: PURPOSE: An ink discharge device of an inkjet head and a control method thereof are provided to uniformly discharge ink from multiple nozzles to the outside by changing voltage applied to the nozzles. CONSTITUTION: An ink discharge device of an inkjet head comprises nozzles(240), a measurement unit(270), and a control unit(280). The nozzles discharge ink. The measurement unit measures the color values of the nozzles based on voltage applied to the nozzles. The control unit compares the color values of the nozzles with target values and changes the voltage applied to the nozzles to equal the color values of the nozzles.
